Abstract: | Young children's apparently sophisticated understanding of language is explained by a simple heuristic which produces responses fortuitously appropriate to many of the messages directed to them. Specifically, the strategy recruits action responses to language unless some element, either linguistic or nonlinguistic, indicates otherwise. Two experiments tested for the existence of the heuristic by examining the responses of children, 19–34 months of age, to sentences susceptible of more than one interpretation. In the first experiment such sentences were spoken in as neutral a context as possible. In the second, the same sorts of sentences were presented in contexts supporting either action or informing responses. The results of both experiments indicate that young children interpret and respond to language in terms of an action-based strategy. Moreover, the observed effects of context show that even young children engage in a continuous, context-sensitive process of interpretation. The data are discussed with regard to speech act theory and its role in a developmental theory of understanding. |
